@PatrickQ the sorting should done inside service,restaurants,shopping and etc that is inside service automotive,home service and etc should be sorted — Arun, Mar 14 '14 at 13:38
Yes, but what is your definition of sorting? Alphabetic? A-Z? Z-A? Do you want to maintain indexes? — Patrick Q, Mar 14 '14 at 13:41
@PatrickQ Alphabetic A-Z and array format should remain same — Arun, Mar 14 '14 at 13:44

It should be as simple as doing this (assuming that $attractionArray is the outer array given above):

foreach($attractionsArray as $key => $innerArray)
{
    sort($innerArray, SORT_STRING);
    $attractionArray[$key] = $innerArray;
}
